California ICC UST Service Technician Practice Exam

Enhanced Leak Detection methods must be capable of detecting a leak rate of at least how many gallons per hour (GPH)?

1. 0.001 GPH

2. 0.005 GPH

3. 0.010 GPH

4. 0.025 GPH

The correct answer is: 0.005 GPH

Enhanced Leak Detection methods are specifically designed for monitoring underground storage tanks (USTs) to ensure any potential leaks are detected swiftly and accurately. The correct answer indicating a minimum detection capability of at least 0.005 gallons per hour (GPH) aligns with regulatory standards and guidelines established to safeguard the environment and the public from harmful substances that may escape from USTs. This sensitivity is crucial in facilitating early intervention, allowing for repairs or remediation before a leak can lead to significant contamination or environmental damage. Methods that can identify leaks at a rate of 0.005 GPH are considered effective for meeting the stringent requirements set forth by agencies overseeing UST regulations. In contrast, options representing lower or higher rates do not align with the recognized standards for enhanced leak detection capabilities. A detection level lower than 0.005 GPH would not be feasible for enhanced methods, while higher rates would not adequately prevent potential environmental hazards. Hence, 0.005 GPH stands out as the regulatory benchmark for enhanced leak detection, underscoring the importance of maintaining vigilant monitoring practices for underground storage tanks.
